Abstract: A flat-formed bolt is divided into an operating portion and a screwing portion, wherein the operating portion and the screwing portion are plat-formed and co-axially correspond to each other. The screwing portion has two opposite sides each formed with a series of teeth, wherein the two series of teeth are staggered relative to each other and each tooth vertically corresponds to an axis of the operating portion and the screwing portion such that the screwing portion can be screwed into a threaded hole previously defined in a work piece.

Abstract: The present invention provides a multi-purpose modular unit, including multiple blocks and adapters. The blocks are provided with multiple side faces and embedded tap holes. The adapters are screwed into the corresponding tap holes of two adjacent blocks. With this adapter, the blocks can be interlocked and assembled as furniture, stationery and toys that can be easily assembled or disassembled depending on various configurations and functions.

Abstract: The planing blade axle includes an axle body and blades assembled externally onto the axle body in a predefined pattern. Tapped holes are arranged onto the blade assembly surface of the axle body for assembly of blades. A pyramidal through-hole is placed centrally onto the blade, so that the blades screw securely into the tapped hole via the bolts with pyramidal end blade. An expanded shoulder is additionally placed at a top of the pyramidal through-hole, so that an expanded flange is placed opposite to the pyramidal end of the bolt. When the blade is screwed by the bolt, a definite and solid positioning effect will be achieved if the flange contacts the expanded shoulder of the blade. The present invention efficiently prevents excessive locking and subsequent cracking of the blade, increasing positioning area, leading to prolonged service life and a more stable locking state with improved applicability.

Abstract: The automatic wood planer includes two front columns separately assembled at both sides of the input end of the feed table of the main body. The pin joint end of the rotary support is screwed at the preset location of the feed table. The swinging end of the rotary support is connected to the lifting seat, so that the cutter shaft is assembled between the pin joint end of the rotary support and the swinging end. The present invention saves more components and reduces the volume and fabrication costs with improved economic efficiency and applicability.

Abstract: A cutter for a wood planing machine includes a block piece having a blade-mounting face that is formed with a positioning groove, and a blade attached to the blade-mounting face and having a plurality of positioning tabs projecting into and engaging the positioning groove.

Abstract: A cutting tool device for a wood planing machine includes a driving shaft having a cylindrical portion and a plurality of insert receiving channels. Each of the channels includes a knife seat wall surface and an abutment wall surface, which confine an accommodating cavity therebetween. The knife seat wall surface has left and right end edges respectively having left and right secant points at a respective junction with an outer wall surface of the cylindrical portion. The left secant point lags behind the right secant point in a counterclockwise operating direction. A planing knife is disposed to abut against the knife seat wall surface. A tightening insert member is inserted into the accommodating cavity, and has front and rear wall surfaces respectively abutting against the planing knife and the abutment wall surface to thereby clamp the planing knife firmly in the respective channel.
